MICHAEL CONLEY, OF CHICAGO, ILLINOIS, ASSIGNOR OF TlYO-TIIIRDS TO JAMESC. RICKETSON AND FREDERICK B. RICKETSON, OF MILIVAUKEE,

\VISCONSIN.

ELECTRIC SIGNAL FOR ENGINES.

SPECIFICATION forming part of Letters Patent No. 442,104, dated December9, 1890.

Application filed October 8, 1889.

T0 aZZ whmn it may concern.

Be it known that 1, MICHAEL CONLEY, of Chicago, in the county of Cook,and in the State of Illinois, have invented certain new and usefulImprovements in Electric Signals for Engines; and I do hereby declarethat the following is a full, clear, and exact description thereof.

My invention relates to electric signals for engines; and it consists incertain peculiarities of construction, as will befully set forthhereinafter and subsequently claimed.

The drawing is a view of part of a marine engine with my inventionapplied thereto.

My invention is an improvement on that set forth in Patent No. 356,792,granted February 1, 1887, to James C. Ricketson for an analogous device;and it consists in a simplification of the same, whereby certain of theparts therein set forth may be dispensed with and an equallysatisfactory result ob-,

tained.

A A are the eccentric-rods of a marine engine.

B 13 represent two of the iloor-beams of the engine-room, between whichis an open space for the free movement of the said eccentricrods.

C 0 represent electric. bells or other annunciators, which may be at anydesired point distant from the engine-roomas, for instance, in thepilot-house. In the drawing I have shown bells; but it will beunderstood that I may use in place thereof or in addition theretoannnnciators of any desired form, such as those used in hotels,telephone-exchanges, or the like, which drop or change position whenelectrical contact is made.

D represents a battery, which may be located at any point in the circuitfound most convenient, and this battery is connected by wire a to thehell or signal 0 and by wire I) to the bell or signal 0 and by wire c toany convenient metallic part of the engine, such as the shaft crank-armsor other metallic part of the engine.

E E represent two properly-insulated me- Serial No. 325,850 (No model.)

tallic contact-pieces having preferabl y springarms e and e,respectively, which extend out over or adjacent to and in the path oftravel of the eccentric-link or other moving part of the engine, theconstruction described being that shown in full lines in the drawing,while in dotted lines these contact-pieces E E are shown adjacent to andin the path of travel of the eccentrierods A A, and from these pieces EE wires d (1 run to the bells or signals C and C, respectively. A switchF is located at any convenient point in the circuit, (as the wire 0,) sothat said circuit may be broken at any time, inasmuch as when myinvention is applied to a boat it is only desired to use the same inentering or leaving port or while making landings.

G is the main shaft of the engine, and II a reversing-lever.

The operation of my invention will be apparent from the foregoingdescription of its construction taken in connection with the drawing,wherein the eccentric-rod Ais shown at its full limit. Now, as the shaftrevolves and the linkf rises the latter will make con tact with thespringarm e of contact-piece E, closing the circuit and ringing oractuating the bell or other signal C. Similarly, if the engine isreversed contact will be made bctween said link and the contact-piece Ee and. the bell or signal C rung or actuated, and thereby the pilot orcaptain (in the illustration given) will always know instantly and allthe time in which direction the shaft is revolving, and thereforewhether the boat is going ahead or backing.

It is obvious that my invention is capable of use with any reversibleengine, whether on land or water, and if found more convenient to attachthe contact-pieces E and E adjacent to the eccentric-rods of the engine,as shown in dotted lines in the drawing, or other moving part of theengine the result would be precisely the same.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The combination, with a reversible engine In testimony that I claim theforegoing I have hereunto set my hand, at Chicago, in the county of Cookand State of Illinois, in the presence of two witnesses.

MICHAEL CONLEY.
